PORTABLE SOLDERlNG-IRON AN D POT-HEATER.

SPECIFICATION forming part bf Letters Patent No. 457,661, dated August 11, 1891. Application filed December 23, 1890- Serial No. 375,642. (N model.)

To all whom it may concern.-

Be it known that we, WILLIAM A. N ICH- oLAs and HENRY BIRNBAUM, of Rapid City, 1n the county of Pennington and State of South Dakota, have invented a new and useful Improvement in aPortable Soldering-Iron and Pot-Heater, of which the following is a specification:

This invention relates to an improved soldering-iron or pot-heater, particularlyadapted for tinuers and plumbers use.

The object of our invention is to produce a portable heater, employing hydrocarbons as fuel, and which can be used indoors or out in all kinds of weather, and one in which one or more irons and a pot may be heated at one and the same time.

With these objects in view our invention consists of a hydrocarbon-burner suitably supplied and incased, and a detachable hood arranged upon the casing covering the burner and adapted to receive the pot-irons, 85c.

Our invention consists, further, in certain details of construction and combination of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the drawings forming apart of this specification, Figure 1 is a side view. Fig. 2 is a top plan view; Fig. 3, detail top plan View of the heater with hood detached. Fig. 4 is a section on line 4 4: of Fig. 2. Fig. 5 is a section on line 5 5 of Fig. 1. Fig. 6 is a section on line 6 6 of Fig. 1. Fig. 7 is a detail view of the pan.

In the practical embodiment of our invention we employ a base 10, supported upon the sides 10, and in the said base, near one end of the same, are formed a series of perforations 10 and in the side, at the opposite end, are formed the perforations 10. An oil-reservoir 11 is arranged upon the base near the imperforate end, said reservoir being of any preferred construction and provided with a filling-vent 11. An air-forcing pump 12 is arranged beneath the base and connected with the upper end of the oil-reservoir by means of the tube or pipe 12 and the coupling-joint 12 arranged in the top of the reservoir, said coupling-joint being provided with a valve 12, whereby the compressed air within the reservoir may be retained therein and serve A band 14 rations being employed to supply the necessary amount of air, and in constructing the heater we employ two vaporizing chambers 0r receptacles 15, arranged longitudinally upon opposite sides of the perforations in the base,

said chambers having narrow ridges or domes 15 formed upon their upper faces, the opposing faces of said ridges or domes having a series of burners or perforations 15" produced therein. The upper face of one of the ridges or domes is also provided with burners or perforations, and over said perforated face is passed the oil-supply pipe 13, the forward end of said pipe being curved downwardly at the forward end of the vaporizing-chamher, and inwardly toward the longitudinal center of the base, being provided with a valved coupling 13 at its lower end, whereby the supply of oil or vapor to the chambers is regulated. A T-coupling 16 connects the vaporizingchambers, the body of said coupling project ing forward, the end of the same being contiguous to the valved coupling, whereby oil or vapor may be forced through the supplypipe and valved coupling into the T-coupling and thence equally into the vaporizing-chambers, where it is burned at the burners or perforations 15". The flames will extend toward the center of the heater, thereby concentrating the heat, and the hydrocarbon in the chambers and T-coupling will be vaporized, and the burners beneath the supplypipe heat the fuel passing through the same and tend to vaporize it.

A casing 17 surrounds the vaporizing-chambers, the said casing extending to the forward end of the base, and at said end is provided with the doors 17, having their opposing edges cut away to embrace the valve-stem 13 when the doors are closed. A gravitycatch l7 locks the doors when in a closed position. The casing extends somewhat forward of the vaporizingchambers, and be tween the forward ends of the chambers and the forward end of the casing is arranged a rigid partition 18, said partition having a perforation 18 made therein registering with the opening of the valve-coupling, and in which the connecting-pipe is secured, whereby a communication is established between these conductors. The partition thus forms a forward compartment, in which is arranged a drip and flash pan 18 adapted to slide upon the base and rest beneath the end of the valved coupling, a vertical plate 18 being secured to the rear side of the pan adapted to cover the perforation in the partition when the pan is slid beneath the coupling, a handle 18 being connected to the pan and projecting without the side of the casing for sliding the pan.

A pan 18 is arranged upon the rear side of the partition 18, said pan 18 being attached to the pan 18 the partition being slotted to permit the attachment and movement of the said pan-18 When it is desired to start the heater, the pans are filled with oil from the supply-pipe, then lighted and afterward slid back beneath the pipe and chamber, thus vaporizing the oil that continues to flow into the chambers, and the vapor issuing out of the burners or perforations 15 will be ignited and the vaporization and com bustion continued until the supply be shut off. When the oil is shut off, the pan 18 is slid beneath the valved coupling to catch any drippings that may take place. A bearing plate or cover 19 covers the forward compartment, said plate extending from one side of the casing to the other, and at its center is provided with a depression 19, adapted to receive a soldering-iron. The oil-supply pipe passes through this plate, as clearly shown. A detachable hood 20 is arranged upon the casingand covers the burners, said hood havinga door 20 hinged at its forward end. If desired, this door may be capable of a swinging and a longitudinal sliding movement in consequence of the peculiar manner in which it is connected to the hood, the upper portion of the door having an elongated slot or guide portion 20 in which works the rod 20, rigid with the hood and forming the forward upper edge of the same. The top of the hood is provided with a circular opening 21, which is closed by alid 22, said lid havinga circular opening 23, closed by a cap 24, which is pivoted to the lid 22.

The device may be used either with or without the hood.

In operation, the reservoir is filled or nearly filled with oil, and theair-pump is then operated, compressing considerable air within the reservoir. The valve in the coupling 13 is opened and oil forced out of the same. The

pans 18 and 18 are now filled with oil, slid back, and lighted. This vaporizes the fuel in the feed-pipes and chambers, and the vapor issuing out of the burners is ignited and further vaporization and combustion takes place, the flames being projected toward the center of the heater, sufficient air being supplied through the perforations in the base and side to support combustion. The doors of the casing may be either opened or closed, and the hood may be used on the casing or detached, as desired. In either cases the soldering iron or irons are slid upon the bearing-plate in the depression of the same andallowed to rest upon the head of the T-coupling connecting the chambers. When the hood is on, the hinged door permits the rapid insertion of the iron and also the withdrawal of the same. \Vhen it is desired to heat a soldering-pot, the hood is necessarily used, the pot being inserted in the opening in the top of same.

On account of the casing and hood the heater is adapted for use out of doors in all kinds of weather.

In a device of the character described, the combination, with a base having supporting sides, one of which is perforated, the base being perforated at the end remote from the perforated side, burners arranged upon the perforated end of the base, and an oil-reser voir arranged upon the opposite end of the base and connected with the burners, substantially as shown and described.
